Web servers are used to deliver content and pages to multiple people, yet the original information is saved from the web server, but is able to be viewed by other computers without them having to host the data center.
When referring to a web server, a person can be talking about the software of a web server, which is the actual application of the computer, or the hardware which is the computer itself.
The most common uses for web servers are:
- Virtual hosting
- Supporting large files
- Bandwidth throttling
- Server side scripting
Web servers do have load limits and most commonly crash due to the overloading of people connecting to the web server in a short amount of time. This can be caused from legitimate traffic, or viruses that cause abnormal amounts of traffic. Some people use firewalls to help prevent this from happening.
